Be it known that L-'CARL GUsTAv Mone- Ninn a citizen of the United States, residing :it-Chicago, in the county of Cook and Stateof Illinois, have invented certain new Iand useful Improvements in- Screens for Passtinger-Cars; and I do declare the .following to be a full, clear, and exact description of the invention, such as will enable lothers skilled `in the art to which itvappertains to. vmake and use the same.

' '1`hisinvention-relates to improvements in screens for passenger cars.

One object of the invention is to provid a car screen having .an improved construcy tion and arrangement of guiding and retaining members whereby the screen is slidably supported in the window frame.'

Another obj ect is to provide means wherebywhen notin use the screen may be readily. pushed up to an out of the way position fentirely above'the window sash and nicansfor yieldingly and removably holding the screen in place' and vpreventing .the-

same from rattling. v

lVith these and other objects in View, the invention consists `of certain novel features trof construction, land the coinbinationwand vai-ran, ;cm'ent of parts as will be more `fully 1 described and claimed. y

"Fig 20 is a detail perspective. view of the operating member which may beemployed for' raising and lowering the screen 'instead of the'scieen operating bars thereof.

My improved screen comprises a traine,

the side, top and bottom bars ofl which cou`- sist of inner and outer members 1 and Q, whichare'preferably formed of metal strips bent into the desired shape. The Ainner members 1 of the screen traine are bentalong their edges, to form-inner flanges 3 and outer flanges 4 which project at right .angles to the facecf the members and in thc face of the' members midway between -said langesis preferably -formed an' inwardly pr 'ectiug reinforcing bead 5 which imparts rigidrkyfto the frame members l. The outer fianges of the frame members have their edges turned and have their outer edges turned outwardly.

tQ a slight degree las shown. The outer edges of themembers 2 are bent to form longitudinally disposed cylindrical tubes 8 which reinforce the frame vmembers and also serve as casings for bperating deviceshereinafter described; Inthe faces of the members2 of the screen are formed inwardly extending strengthening beads 9 which serve to reinforce this part of the members. j

In assembling the inner and outer members of the screen frame the outwardly curved flanges 4 on the outer edges of the screen members 1 are engaged withthe inner sides ofthe tubes 8 of the outer members'whilethe edges of the inner iianges 8 having the ribs 6 are sprung into engagement with the inwardly projecting flanges 7 of the outer members 2 of\the screen frame.

By constructing thelin'ner and outer members of the screen frame as herein shown4 and described it will be seen that when said members are engaged inthe manner de scribed they will be securely fastened together and cannot be separated without the use of .a 'proper tool and the application of considerable force.

Arranged in the frame of the screen is'a covering 10 of fine mesh wire netting'- the edges of which are firmly gripped and fas-v tened between the engaging inner and outer flanges Secured te the tube 8 of the outer member 2 of the upper cross bar of the screen frame is a weather strip 111 formed of a piece of l suitable fabric folded lengthwise and having its inner edges stitched together and inserted' into the tube 8s' of the upper cross bar of the screen frame between the free edge of the tube and the adjacent portion of the frame member 2. The folded outeredge of the weather strip projects a suitable Adistancebeyond the Vouter side of the frame member 2 while the 'stitched inner`edges project into the tube and have. engaged therewith a retaining rod 12 as clearly shown in Fig. 6 of thedrawings.v The weatherstrip 11 when thus arranged will engage the adjacent part of the outer sash of the window and thus form an air tight engagement between the upper portionof the screen and the outer sash.

The screen frame is preferably braced by means of a vertically disposed tubular censprings 1 the members 1 and 2 of the screen.'

to the inner flanges 7 of theouter screen members 24 of the upper and 'lower bars of the frame'as shown. Detachably engaged 4with the right hand side bar of the screen frame is a right hand guide shoe 14 comprising a substantially U-shaped metal plate the sides of which have a close sliding engagement with the outer sides of the members 1 and 2 of the left hand 'side bar of the frame, while the' loop shaped outer edge ofthe plate 'embraces the tube 8 of the .outer member 2 of this "side of the screen frame. The outer sidejof the shoe 14 is off setslightly as at 15 toclosely fit the oifset vedge of thetube 8 as shown. rlhe loop shaped therein one or moreI which are adapted 'to engage the adjacent outer surface of the tube 8 of the member 2 of this. side of the screen whereby the shoe 14 i'syieldingly heldin spaced relation to said tube and is held in yielding 'engagementwith the right hand screen guiding member hereinafter described.` @n the upper end of the guide shoe 14 is a hook shaped lug 17 which is adapted'to engage the outerv end of the tube 8 of the upper ing the shoe 14 in position fon the screen frame. i

Engaged with the left hand side bar of the screenis a left hand guide shoe 18 which comprises a channel shaped plate andV is 14 on the right hand side of the screen frame. The shoe 18 has its side members slidably engaged with the outer surface of the members 1 and 2 of the left hand side bar of the screen frame and is provided .with a fiat centrally disposed spring 19 'and at its 20. The spring 20 is adapted to engagev the lower end of `the tube 8 of the outer member 2 of this side of the screen while the spring nism hereinafter described whereby the shoeL is spaced from the'tub'e 8 and left hand side bar of the-screen and held in yieldingly slidable engagement twith the. left 'hand' screen* guide. By thus arranging the shoe 1\8"and the spacing mechanism therefor on the left hand side of the screen frame and the guide shoe 14 on-the right hand side maybe held in operative position in window frames which Vary' slightly in width and may be readily removed from the window frame as will'be hereinafter more fully described. The shoe 18 is held in sliding engagement with the upper end of the side bar of the screen by a guiding and retaining plate 21 which is soldered or otherwise rig- 19 is engaged bya shoe adjusting mechathereof it will be seenthat the screen frame ends rigidly secured in any suitable manner y outer. edge of the shoe 14 has arranged Hat vertically disposed cross bar of the screen frame thereby holdconstructed in the same manner as the shoe lower en d isprovided with asimilar spring 'wie idly secured at its .inner end to the inner member of the upper cross bar of the screen frame and hasy at its upper edge a hook shaped iiange '22 which engages thetube 8 .5 on `theupper cross bar of theframe. The outer portion of the'guide plate 21jis piiset from the adjacent outer surface'of the side n bar of the frame a sufficient distance to form a. space with which the adjacent side of the shoe .18 is slidably engaged. .In the offsety lend of the plate 21 is formed a channel 23 with which is engaged a' short rib or bead l23 struck in or formed on the side of the shoe wherebythe upper end of the'latte'r is held in Asliding engagement with the upper end of the screen frame. The lower end of the shoe 18 is provided `with a frame engaging bail 24 the loop-shaped inner end ofv which is arranged at right angles to the side bars'thereof and is adapted to engage be-. neath the tube 8 ofthe lower'crossbar of the screen frame while the sides of the member 24 engage the opposite sides of said lower cross bar as clearly shown in the drawings. lVhen' thus arranged the bail shaped member 24- holds the lower end o'f the sh'o'e, 18, in sliding engagement with the ldwer left hand corner. of the screen. frame and together with the plate 21, holds said shoe against' Vertical movement on thel screen frame but permits the latter to be readily7I` adjusted laterally on`the left hand side of the screen frame.

Secured in the upper end of the shoe '18 is a spring frame supporting catch 26 which corresponds With a similar catch 27 securedy towthe upper end of the tube 8 of the left -hand side ba'r of the frame, Said catches 26 and 27 having their upwardly projectingv ends bent to form catch lugs 2S which are engaged with the screen guiding members hereinafter described-to -yieldingly hold the screenin closed andopen positions.

The screenr'guiding members herein referred to comprise .right and left hand chan? nel shaped bars 29 and 30, having on their outer .edges laterally extending gripping flanges 31. The bars 29 and30 are detachably engaged with right and left hand tu' bular sash parting strips32 and 33 which `are arranged between the 'inner and. outer sashes 34 and 35 of the window frame. The left hand part-ing strip 33 is riveted or otherwise rigidly secured tothe left hand side of the window frame 36 which is herein shown as being formed ot pressed sheet metal. The sashes 34 and 35 are slightly narrower than the width ofthe window frame and between said sashes and the right hand side 'of the window lframe 36 which is here' shown as being formed o'pressed 'sheet metal, are narrow spaces 37'with vwhich are engaged springs 38 whereby the sashes are dow frame is a spacing bar 40 to which the 'when thus arranged and secured between the.

held against rattling.r In thus constructing 55 the sas es and window frame a space 39 is formed between the right hand parting strip 32 and the .side of the windowA frame and ar-l 4ranged in this spade and riveted or otherwise secured to the'adj'acent side of the wi'nright hand parting strip 32 is detachably 70 secured.-

The parting strip 32 is detachably secured to the spacing bar 40 at its upper end by an elongatedoiiset hook 41 'which is preferably 75 constructed and 'bent inwardly from the bar' andis adapted to engage a slot 42 in the parting strip 32 near its upper end as shown. In' the lower end oit the parting vstrip is formed' a rectangular notch. 43 which -is adapted to be'engaged with a T-shaped lug 44 formed on the lower end of the spacing `bar 40. The partingstrip 32 is further se- 'cured tothe barI 40 mtermediateits ends by means of spring clips45 which aresecured g5 to the Ainner side of the parting stripand l have their lower. ends lprojecting through slots 46 in the rear wall ofthe parting strip. T 31e ends .of the clips 45 'after passing through the slots 46 extend downwardly bi) and form catches 47 which are adapted to.

be sprung into engagement with slots 48 in the adjacent portion of the bar 40 as shown@ I The inner ends of the spring clips 45 pro'- )ect upwardly and OlHl catches with' which S are engaged hooks 49 secured .t0 the inner side of the right hand screen guide 29 Whereby said guide is detachably securedto the right hand parting strip. The left hand parting strip 30 has secured to its inner side,- `m0 hooks 50 which correspond to thev hooks 49 of the right hand screen guide and are adapted tube-engaged with upwardly pro- -je'cting hooks orchps v5.1 arranged on the inner side of the left hand parting strip said clips' or hooks 50 beingpreferably cut and struck inwardly from said parting strips as shown.

The parting strips 32 and 33 are in the form' of hollow or tubular rectangular bars 110 as herein shown, said bars having in their inner sides vertical passages with which the right and left hand screen guides are engaged when said guides are secured to the parting stripsin the manner described.

Riveted or otherwise vsecured tothe inner sides of the screen guides 29 and 30 are weather strips 51 the-edges of which pruject beyondl the ottset side edges 31 of thescre'en guidesandare clamped between said offset edges ofI the Ascreen guides and the adjacent edges of the parting stri-ps 32 and 33 as'. clearlyshown in Fig. 4 of the drawings. T-.he project-ing edges' of the weather strips ilo - the slot as shown. 'Ihe `outer end of the and projected link 52 is rounded and when said link; is

swung downwardly to a horizontal position laterally through the slot' 53 and beyond the outer side of the tube 8, said rounded outer end will be brought into engagement with the spring 19 on the inner side of the shoe 18 and vwill yieldingly force said shoe outwardly into close sliding engagement with the left guide member of the parting strip '33 thereby ,holding the screen'in sliding engagement with the guide members on the parting strips of the win dow frames. -When the link 52 is in an operative position as just' described'the screen will be held against removal from the screen guides and in order to permit the removal of the screen I provide means orretracting r the link 52 into the tube 8 which will permit the screen frame to be slipped laterally in the shoe 18 a su'liicient distance to permit the shoe 14: and opposite side of the screen to be disengaged from the right hand screen guide as will be readily 'understood rIllia retracting mechanism for the cam link 52' comprises a link retracting rod, 55 which is arranged in the upper portion of the tube 8 and has secured to its lower end 'a rod centering and guiding block 56 and to its upper' end a cylindrical guiding and cen tering black 57 having in its upper enda' The lower end of thev threaded socket 58. rod 55 is pivot-ally connected to the inner end k'ot' apair oi retracting links 59 the outer ends of which are pivotally connected to the outer end of the cam link 52 whereby when the rod 55 is drawn upwardly in the tube 8 said links 59 will swing the link 52 upwardly thereby retracting the same'intor:

the tube and releasing the shoe 18 as hereinafter described. The rod 55 is4 drawn upwardly in the tube 8 to retract the link 52 by means of an operating screw 60 wh'ich is revolubly mounted in a tubular bearingI block 61 rigidly secured in the upper portion o t the tube 8 and has its threadedlower end engaged with the threaded socket 58 in the block 57 secured to the upper end of the`rod The screw 60 is held in revoluble engagement with the block 61 by 63 or other suitable fastening means adjacent the inner end oi the block 61 as shown. The head of the screw 60 when thus arranged is disposed adjacent to the upper end a collar 62 which is .tastened on the screw by a rivet of the tube 8 and is provided with a slot with which a screw driver may be engaged when inserted in the upper end -of the tube and the screw 60 thus turned in the proper direction for drawing the rod 55 upwardly or pushing said rod downwardly to retract or project thetlink 52 as will be readily understood.

In order to permit pushed upwardly to an inoperative position above'the upper sash of the window frame I provide suitable tubular screen operating rods 64- one of which is slidably engaged with the lowervportion of the tubes 8 of the outer members 2 of the side bars of the screen frame. The tubular rods 64 are projected up into and entirely inclosed in the .tubes Sv'lien the screen frame is in a lowered or inoperative position and when said screen is raised the rods64: are automatically retracted rom or held down while the screen is raised and when the screen has the screen frame to be i y been raised in -the usual manner to the y height of the lower bar of the open inner sash and cannot in this manner be further raised the rods 64 are automatically locked in their projected positionsv and may be grasped by .suitable handles `65 formed by inwardly extending lugs' on the lower ends of the rods and said rods employed to further'push the screen frame" upwardly to an tout oft' the way' position above the window sashes.

The locking mechanism for holding the screen operatingrods 64 projected, comprises bolts 66 which are slidably` mounted in tubular casings 67 `which in turn are secured in the-outer` ends ot the tube 8 on the lower cross bar of the screen frame as shown. The 'bolts 66 -are projected and yieldingly held in a projectedw'position by coiled. spring 68 arranged between-the inner .en d of the bolts and -the'closed inner ends ofthe cas ings 67. The outward movement of the bolts by the springs 68 is limited by studs 69 secured in the bolts and yengaged with slots 70 inthe casings as shown. The bolts 66 when projected from thecasings 67 also project beyond the `ends of the tube 8 and are adapted to engage apertures 7l in thc inner sides of the upper ends of the tubular operatingrodsd when the latter are projected from the tubes 8 on the side bars of the screen frame thereby locking said rods in their projected positions to permit the same to be employed for raising the screen frame in the manner described.

In order to retract the bolts 66 to permit the operating rods 64 to be retracted into the tubes on the side bars of the window frame, I provide bolt retracting plungers 7 2 one of which is slidably mounted in each of the rdds 64 below the holes 71 therein. The plungers 724 have their upperends beveled on their inner sides to engage the projecting iis i ends of the bolts sothat when the plun-L vgers are :forcedv upwardly` the bolts 66 will l be pushed back intheir casings against the pressurenof their springs 68. The -plungers 7.2 have secured thereto operating rods 73 which extend downwardly'through the tubular screen operating 'rods and projectna slight'distance below the lower e'nd's of said rods 64' sothat when the screenfrarne is lowered the projecting ends of the rods 7 3 will `be brought into engagement with the window sill ands-aid rods and theyplungers 72 thusforced upwardly in i the rods '64 thereby I bringing the beveled upper ends of the plun-I gers into engagement with the ends ofthe bolts 66 and retracting the latter in the manner described. The plungeroperating rods 73 are retracted or forced downwardly Aso as soonas the screen frame is raised and the outer ends of the rods disengaged from the window sill, by means of coiled springs 74 which are arranged o-n said rods between stop collars 75 secured in thetfubular rods 64 and combined stop and guide lugs .76 secured in the lower ends of the plunger operating rods 73 las shown. The 'lugs 76 project beyond one side of the rods .73 and engage slots 77 in'the adjacent side of the screen operating rods .64 and therebypreguides 29 and 30. The enga-gement of the of the tubes .8 on the vscreen frame when the spring catches 78 with the recesses 79 is suf iicient-to pull the rods 73 and. the tubular screen operating rods 6 4 downwardly out latter is raised. The rods 7 3 and-64 are thus projected or pulled down until the holes 71 in the upper ends of the rods 64 are brought opposite tothe bolts 66 which will then be projected into said holes 7l thereby locking the rods in an operative position. When the rods are thus locked a further upward movement of thel screen frame will disengage the springPv catches 7S from the recesses 79 thuspermitting the rods tobe carried up with the screen frame. Secured in the upper ends' of the rods 64 are pressure springs 64 which are preferably constructed as shown and have t-heiroifset loop shaped upv per'ends in yielding frictional engagement with the inner sides of the outer portions of the tubes 8whereby the' nnner ends of the rodsV 64 willbe forced against an'd held in* tight frictional engagement `-with theoppolatter are prevent tubes 8, so that the bolt holes 71 therein willv l always be lnposition to receive the bolts 66 site sidesjof thetubesL S so that the outer ends of .the v'-bolts66 will readily 'enter the apertures7l inthe rodswhen said apertures' are brought opposite to the bolts.

- -On the lower ends of the screen ides 29 and 30 are inwardly extending stri ing lugs 80 with which the lower ends of the plunger operating rojds 73 are engaged wwhen the screen frame is pulleddown to an open position, said lugs preventing the ends of the rods78 from marring the window sill.

'the upper ends of the screen guides are formed upwardlyextending catchl lugsI 81 which are engaged beneath the lower ends of screen guide'extension bars 82 securedto v t-he upper ends vof the parting strips on the opposite sides of the window l:'rame,'said ex-y v tenslon guides forming continuations of the .lowerguide vmembers to receive the .guide 'shoesfof the screen frame when the latter is pushed upwardly to its extreme uppermost position in the window frame.

Ontheuf' per endsy of thel extension bars 82 of t e:

are engaged) when the screen has been' pushed to its uppermost posit-ion'A and 'by screen guides are catch lugs 84 with which the lugs- 28 onith'e spring catches 26 and 27,'

means of which the screen is retained in'this position. In the lowerscreen guiding members 29 and Oatpoints adjacent to .the upper end of the screen frame vare4 'lacking j, notches 85 with which the lugs 28 on said .spring catches 26l and 27 are engaged when the'screen frame is in a full lowered-position and whereby thescreen'will'be held down in tight engagement withthe window sill and may be manually raised when desired. Secured in the ytubes 8 'of the side members of the screen are guide lreys'V 8"i which engage guide slots 77 in the outer sides of the tubular screen 'operatiig rods 464: wherebyl the fromturning in the when'the rods 64 are pulled outwardly-from the tubes 8.

In the inner member 1 of the lower cross ba'r \of the window frame are formed reces'ses.l` 86 which provide .hand holds with whic'hythe lingers of the hands may be engaged for'raising the screen frame until the lowerjbar thereof'is brought adjacent to the lowerl bar ofthe inner sash and the operating rods 64 projected to permit the vfurther upward 'movement of the screen. In said inner member of the lower cross bar of Vthe screen frame isl also formed a centrally disposed recess 87 with which isadapted to Ibe engaged the hook shaped upper end of a screen operating rod 88 which may be provided to take the place of'the screen operat- 'ing rods 64 for raising the screen' to its ex- .izo

treme upward position or for pullingthev same down to a position where the recesses 86 1n the lower cross bar thereof may be j reached. Theoperating rod 88 when not in luse is disengaged from the recess 87 and 'inay be kept in any suitable place for use lwhen needed.

` It will be noted that by'providing the springprojec'ted guide shoes for the side bars of the screen `trame the latter will slide freely in the window frame and will close tightly against the window sill even .though the windowfraine is not perfectly square or true as the spring projected guide shoes will permit the screen Jframe to adjust itself to any irregularities of thewindow frame. From the foregoing-description taken in connection with tlie"' accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation. Various changes in the form, proportion and the minor details of construction may bev resorted'to withoutdeparting from the principle or sacriticing any of the advantages of the invention as claimed.
